Three Things to Do Before You Are 18
Are you bored with your daily life? Here are some things you should try before you are 18.
★Learn to swim
Seriously, this is so important that it can save your life. If you can’t swim well, you won’t be able to dowater sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make sure you do it.
★Try at least one kind of team sports
Being a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and make many friends.
★Collect something
One of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends. The best way to collect is to have a special album to put your collection in and to write what each thing means to you. That way you won’t forget.
1. The most important reason for learning to swim is that ________.
A. you might feel well
B. it can make you healthy
C. you might easily do lots of things
D. it can save your life
2. The writer tells us that one of the best hobbies is to ________ .
A. collect something
B. do some water sports
C. send letters to your friends
D. play basketball with your friends
23. The passage is mainly about ________before you are 18.
A. good habits to keep
B. skills to have
C. things to do
D. sports to play
B
Improvements to energy efficiency, such as LED lights, are seen by many authorities as a top priority for cutting carbon emissions. Yet a growing body of research suggests that arebound effect could wipe out more than half of the savings from energy efficiency improvements, making the goals of the Paris Agreement on climate change even harder to hit.
A team led by Paul Brockway at the University of Leeds, UK, looked at the existing 33 studies on the impact of the rebound effect. First comes the direct rebound: for instance,when someone buys a more efficient car, they may take advantage of that by driving it further. Then comes the indirect rebound: fuel savings leave the owner with more money to spend elsewhere in the economy, consuming energy.
Although the 33 studies used different methods to model the rebound effect, they produced very consistent estimates of its impact, leading the team to conclude that the effect wipes out, on average, 63 percent of the anticipated energy savings.
“We're not saying energy efficiency doesn't work. What we're saying is rebound needs to be taken more seriously,” says Brockway.
The idea that increased efficiency may not deliver the hoped­for savingsdates back to the Jevons paradox(悖论), named after the economist William Stanley Jevons, who, in 1865,observed that more efficient coal use led to more demand for coal.
If the rebound effect does prove to be as big as suggested, it means future global energy demand will be higher than expected and the world will need far more wind and solar power and carbon­capture technology than is currently being planned for.
But that doesn't mean nothing can be done to limit the rebound effect. One answer is to double down on energy efficiency and do twice as much to achieve the same effect.
4. Which of the following is a rebound effect?
A. A man uses LED lights to cut carbon emissions.
B. A company uses coal more efficiently to reduce waste.
C. A family saves money by using energy­saving devices.
D. A lady spends savings from her fuel efficient car on more clothes.
5. How did Paul Brockway's team carry out their research?
A. By interviewing economists.
B. By analyzing former studies.
C. By modeling the rebound effect.
D. By debating about the Jevons paradox.
6. What would Paul Brockway probably agree with?
A. Authorities should dismiss energy efficiency.
B. Worldwide efforts to preserve energy are in vain.
C. The rebound effect helps protect the environment.
D. More attention should be paid to the rebound effect.
7. What's the author's attitude towards limiting the rebound effect?
A. Positive.
B. Pessimistic.
C. Doubtful.
D. Disapproving.
C
Researchers say spicy tomatoes could soon be on the menu thanks to the rise of gene-editing technology.
It's not the first time that experts have claimed techniques could develop fruit with unusual features: scientists have already been looking at changing the color1 of kiwi fruit and bettering the taste of strawberries.
But researchers inBrazilandIrelandsay such methods could also offer practical advantages, with hot tomatoes offering a new way of harvesting the pungent chemicals found in peppers known as capsaicinoids, which make food taste “hot”.
“Capsaicinoids are valuable. They are used as painkillers and there are some researches showing that they promote weight loss,” said Agustin Zsogon from a Brazilian university, a co-author of a new article arguing for the benefits of engineering hot tomatoes.
Writing in the journal Trends in Plant Science, the researchers say peppers are difficult crops to grow and low productive. Worse still, it is tricky to keep the pungency of the fruits table. By contrast, tomato production is high and the plant is well-studied. “You could produce the capsaicinoids in a more cost-effective manner,” said Zsogon.
Tomatoes and peppers developed from a common ancestor, but separated about 19 million years ago. “All these genes to produce capsaicinoids exist in the tomato, they are just not active,” said Zsogon. “Using gene-editing technology, it is likely to switch these genes back on in tomatoes, making the fruit more special”, he said.
8. Why are the tomatoes made hot by the researchers?
A. To test the gene-editing technology
B. To improve the amount of the tomatoes
C. To explore ways to harvest more capsaicinoids.
D. To make the tomatoes more delicious.
9. For what purpose can capsaicinoids be used according to the text?
A. To put on weight.
B. To ease the pain.
C. To improve sleep.
D. To better the look.
10. What is Zsogon's attitude to the gene-editing technology?
A. Confident.
B. Critical.
C. Anxious.
D. Doubtful.
11. What's the main idea of the text?
A. An introduction to gene-editing plants.
B. Creating hot tomatoes by gene-editing.
C. Problems with capsaicinoid production.
D. The procedure of producing capsaicinoids.
D
Scientists have long sought to prevent sharp memories from dulling with age, but the problem remains unsettled. Now research published in Scientific Reports suggests virtual reality might help older people recall facts and events based on specific details.
The study involved 42 healthy older adults from the San Francisco Bay Area. Half spent a dozen hours over four weeks playing a virtual-reality game called Labyrinth; they wore headsets and walked in place, walking virtual neighborhoods while completing small tasks. The other half, in the control group, used electronic tablets to play games that did not require recalling details. After 15 sessions (期), the latter performed roughly the same as before on a long-term memory test. But the Labyrinth players gain an improvement in memory through the VR game. A scientist Peter Wais of the University of California said the improvements brought them up to the level of another group of younger adults taking the same memory tests.
Meredith Thompson, an education researcher, studies learning through VR games but was not involved in the new study. It would be great to actually follow people over time and see what this type of game does for long-term memory. She says, adding VR can provide greater involvement than other games. Wais's team is now investigating how long the observed effects last and which elements of the training have the most impact.
A cognitive (认知)psychologist, Daniel Simons, who was also not involved in the study, notes experiments with other games that claim to train the brain have often failed to evaluate this. And it remains unclear how test performance in a laboratorysetting might translate to real-world situations. The outcome, Simons notes, “needs to be repeated, ideally with a much larger group, before it’s treated as a strong finding.”
For now, Wais says, the team hopes its studies with similar-sized groups will help draw funding to test the game in a larger pool of participants.
12. What is the passage mainly about?
A. People's memory gradually fails as they age.
B. People of different ages should play VR games.
C. Virtual reality changes people's memory.
D. Virtual reality improves older adults' memory.
13. What is Meredith Thompson's attitude toward the research?
A. satisfied.
B. enthusiastic.
C. cautious.
D. concerned.
14. According to the scientists, the research needs to be improved due to ________.
A. the lack of financial support.
B. the limited pool of participants.
C. the unsatisfying test performance.
D. the impractical application in real world.
15. Where may the passage come from?
A. A novel.
B. A review.
C. A magazine.
D. A guidebook.
